Cell image segmentation is the base of further medicinal analysis, and the quality of segmentation has a great influence on cell identify and analyzing. Although there are many segmentation algorithms on recent papers, it is difficult to find one that can be applicable to general cases, and the adhesive cell will affect the cell analysis. So this paper developed a cell image segmentation method using...
A method for threshold selection to detect edge width of objects in the image was presented. Three order spline wavelet was choosed to complete multiscale wavelet edge detection and wavelet edge module values were obtained. After properties of these data was analyzed, a method for threshold selection was proposed using half of maximum of wavelet edge module values. Edge width of objects in the image...
In accordance with the two-dimensional structural dependence of color cartoon image and the entropy coding theory in data compression, a method of color cartoon image lossless compression by eliminating the structural redundancy is presented. At first it is proved that the entropy of image can be reduced by way of removing the solid region. Then the method of removing the structural redundancy is...
A real-time algorithm is presented to detect moving targets in underwater complex environment. The difference image is obtained by subtraction operation in frames of image sequence. An appropriate threshold is selected and the binary image of the difference image is obtained. Every part of the binary image is segmented into one single image by image segment algorithm. A definition of linear level...
In this paper, a hybrid method for the segmentation of medical ultrasound images is proposed. The method is composed of two parts as region growing and region merging. First, we initially segment the images into many small regions using a region growing method. The region growing algorithm is based on some pixels we specially choose as growing centers. The initially segmented images acquired from...
While CT colonography (CTC) is becoming a more prevalent and accepted method to diagnose colon cancer, the leading cause of nondiagnostic segmental evaluation of CT colonography is colonic diverticular disease (CDD). An essential element of detecting CDD in conjunction with CT colonography (CTC) is the accurate segmentation of the colonic wall. We have developed a level set based method to determine...
